What files do I need?

Jailbreak Software 1.1.2

iPhone 1.1.1. firmware file (optional)

1.1.2 Jailbreak

**** NOTE: This method currently requires you be on 1.1.1 of the firmware. If you are on 1.1.2
you must downgrade prior to being able to use this jailbreak. ****


Step 1: Downgrade to 1.1.1 (if required)
*** NOTE: errors 1015 is expected at the end of the process. Continue reading to understand. ***

1. Download the 1.1.1 ipsw firmware file from Apple. If the downloaded file has the extension
“.zip”, please remove it and modify it to end up with a filename ending in _Restore.ipsw

2. Reboot your iPhone holding the top (power) and home buttons BUT release the top button 10
seconds into it (right after the screen goes dark) and continue to hold the home button until
iTunes detects the phone in recovery mode. The iPhone screen will appear to be off, but start
iTunes if not started yet .

3. Restore your iPhone by pressing and holding the ‘Shift’ key on windows or ‘option’ key on Mac,
then click ‘restore’ to select the 1.1.1 firmware file you downloaded earlier. The restore should
go through and errors at the end with error 1015. However you will notice that the iphone is in
DFU mode with the connect to itunes screen from 1.1.1.

4. In order to kick the phone out of that mode I just had to launch iNdependence version 1.2.5
and wait a minute or so. If you are using iTunes 7.5 you will have to get a MobileDevice from a
previousv version in order to run Independence.

list. And thereafter every time you push the homebutton you just slide the “emergency call”
slide, then enter 0 , press call, press hold, press decline.

menus with favorites, you can edit contacts, do a test ride on keyboard, take photos etc.
